Reputable VW repair shops in Buffalo/Rochester/Niagara/Ontario?

[doubt at inwave.com (Nate Mellom)]

Just got back from an Easter vacation with my in-laws, and was talking 
to my brother-in-law.  He has an Mk4 Jetta TDI that needs some work, but 
he's leery about the mechanic he's been taking it too.  Anyone know of a 
decent shop or two in upstate NY I can refer him too?  He lives in 
Medina, NY, a short hop from Buffalo and Rochester, and close to Canada.

TIA!
